I got out of my rut by attending some quilt shows ... the use of colors in some of the quilts .. really gave me the push I needed.
Everythime I woould leave a show, feeling like an hack quilter, I realized it was my own restriction on color that was keeping me from having the "look" of some of the show pieces.
Sometimes now when I am selecting fabrics , I have to think about it as I am selecting for my "other personality" that way I can mentally free my self. That "other" quilter in me seems to do pretty well.
